[Feat]: Reasoning Engine - support for environment variable

[darrenchiu]

Is your feature request related to a problem? Please describe.

Our agent would leverage some third party API, but we don't want to hard code these API keys in the code. We would like to be able to supply the keys using environment variables for best security practice

Hi @darrenchiu! The recommended way to handle this is to use Secret Manager within a given Python function / tool, which will allow the secret to be securely retrieved by the deployed Reasoning Engine agent. You can implement this within your tool(s) using the sample code shown at https://cloud.google.com/secret-manager/docs/access-secret-version. Let me know if that approach works for you or if you run into any issues. This is also something I can pass to the Reasoning Engine team that we can write up more thoroughly in our documentation and sample notebooks.
